Abstract: This talk describes a vision of processing-centric networks that unify In-Network computation and programmable communication. This convergence of computation and communication enables a high degree of flexibility in the design and operation of distributed applications that run „on top“ or „within“ these networks. We specifically consider some of these applications that must adhere to given performance requirements, e.g., on timing, with a main focus on Multimedia Systems. Major challenges to the design and operation of processing-centric networks lie in the coupling of the programmable control of networks with application and network models that are fed with real-time feedback data. The aim of such coupling is to provide flexibility in combination with provable performance guarantees.

Bio: Amr Rizk received the doctoral degree (Dr.-Ing.) from the Leibniz Universität Hannover, Germany, in 2013. After that he held postdoctoral positions at University of Warwick, UMass Amherst and the TU Darmstadt, Germany. From 2019 to 2021 he was an assistant professor at Ulm University, Germany.

Since 2021 he is a professor at the department for computer science at the University of Duisburg-Essen, Germany.  He was a recipient of the Excellence in DASH Award at ACM MMSys 2016 and the Best Paper Award at ACM Middleware 2017 and ACM MMSys 2023. He is interested in performance evaluation of communication networks, stochastic models, and their applications to distributed systems.
